If you’re looking to enhance the look and durability of your outdoor patio, grouting a patio with mortar is an essential part of the process.

At ADC Pressure Washing & Exterior Cleaning, we specialize in professional patio cleaning and maintenance services — including expert grouting of a patio with mortar. In this blog, we’ll walk you through everything you need to know about the process, benefits, and how our team can help transform your outdoor space.
Why Grouting a Patio with Mortar Matters
Grouting is the process of filling the gaps between paving stones or slabs with a binding material — in this case, mortar. It plays a crucial role in the overall integrity and longevity of your patio.
Key Benefits of Mortar Grouting for Patios:
- Stabilizes paving stones to prevent shifting or loosening over time
- Prevents weed growth and moss in the joints, keeping your patio clean and safe
- Enhances water drainage by filling gaps and preventing pooling
- Improves the overall appearance, giving a neat, polished finish to your patio
- Protects against damage from freeze-thaw cycles during colder months
Without proper grouting, patios are vulnerable to damage, becoming uneven and unsafe. Mortar, unlike loose sand or polymeric grout, offers a robust and long-lasting solution.
What is Mortar and Why Use it for Patio Grouting?
Mortar is a mixture of cement, sand, and water that hardens to form a solid bonding material. For patio grouting, a stiff mortar mix is applied to the joints between paving slabs or stones.
Advantages of Using Mortar:
- Stronger and more durable than sand or resin-based grouts
- Resistant to erosion from rain and foot traffic
- Provides excellent bonding strength, securing paving stones firmly
- Versatile for various types of patio materials — concrete, natural stone, bricks, and more
At ADC Pressure Washing & Exterior Cleaning, we use the highest quality materials to ensure that your mortar grouting lasts for years, even in unpredictable British weather.
How to Prepare for Grouting a Patio with Mortar
Preparation is vital for a successful mortar grout job. If you skip the prep, the mortar may not bond properly or last.
Preparation Steps Include:
- Clean the Patio Thoroughly
- Remove all dirt, moss, and debris from between the paving slabs. We recommend professional pressure washing to clear out stubborn grime and algae.
- Remove Old or Damaged Grout
- If your patio already has grout that’s crumbling or missing, carefully rake out the old mortar to a depth of at least 20mm.
- Check for Loose Paving Slabs
- Any loose slabs should be reset on a stable bed of sand or mortar before grouting.
- Ensure Dry Conditions
- Mortar works best on dry surfaces. Avoid grouting on wet days or if rain is forecast within 24 hours.
Step-by-Step Guide to Grouting a Patio with Mortar
Here’s a straightforward step-by-step process you or your professional team can follow when grouting a patio with mortar:
1: Mix the Mortar
- Use a mix ratio of 1 part cement to 4 parts sharp sand.
- Add water gradually to create a stiff but workable mortar consistency.
- Mix thoroughly until you have a uniform paste without lumps.
2: Apply the Mortar
- Using a pointing trowel or grout bag, apply mortar firmly into the joints.
- Press the mortar deeply to fill the gaps, ensuring no air pockets remain.
- Work in small sections for better control.
3: Compact and Smooth the Joints
- Use a jointing tool or the edge of a trowel to compact the mortar and create a neat finish.
- Strike off any excess mortar from the slab edges before it sets.
4: Clean Excess Mortar Quickly
- Before the mortar hardens, clean any residue off the patio surface using a damp sponge or brush.
- Take care not to disturb the mortar in the joints.
5: Allow to Cure
- Mortar takes approximately 24 to 48 hours to set properly.
- Avoid foot traffic or heavy use until fully cured.
Tips for Best Results When Grouting a Patio with Mortar
- Work during mild, dry weather for optimal curing.
- Use sharp sand with the mortar for better strength and durability.
- Wear protective gloves and eye protection when handling mortar.
- Clean your tools promptly to prevent mortar buildup.
- For wider joints (more than 15mm), consider using a stronger mortar mix or specialist jointing compounds.
